Furman SPR-16Ei Stable Power AC Voltage Regulator

Furman SPR-16Ei Stable Power AC Voltage Regulator

For over 40 years, Furman has led the development of AC power solutions for professional audio, video, and broadcast applications. The SPR-16E i is a revolutionary advancement in stable power delivery, designed to meet the extreme demands of high-performance systems. Unstable AC voltage can severely impact audio and video quality, limiting the performance of amplifiers, subwoofers, and sensitive components. Whether from voltage drops that reduce sonic impact or excessive voltage that shortens component lifespan, the SPR-16E i ensures a constant, regulated power supply, allowing systems to perform at their full potential.

The SPR-16E i features Stable Power AC Voltage Regulation Technology, which maintains steady voltage without generating excess heat or mechanical noise. Its zero-crossing solid-state technology delivers peak current without the limitations of conventional AC regulators. Furman’s Linear Filtering Technology further enhances performance by eliminating RF and EMI noise, preserving the clarity and depth of both audio and video signals. Additionally, the unit’s Series Multi-Stage Protection provides industry-leading surge suppression without degrading over time, ensuring maximum protection without sacrificing performance.

With real-time digital voltage and current meters for precise monitoring, the SPR-16E i guarantees reliable power in any environment. When paired with Furman’s IT-Reference 16E i, it delivers an unparalleled combination of stable power and discrete symmetrical AC filtering. The result is superior sound and visuals—crisper images, deeper blacks, and a more immersive audio experience, making it an essential component for high-end home theaters and professional AV setups.
